Lines: 41 <-bug food I too am using Crosstalk on the IBM PC. But while I am very happy with the program, I must report that it does NOT do a complete emulation of the vt100. Several things it is missing are listed in the manual. Among them are (I am speaking from memory) 132 column mode, double wide characters, double high characters and smooth scroll. There are also some things which the manual does NOT mention that Crosstalk does incorrectly. 1) It sometimes scrolls the display when it should not. 2) It does not ignore escape sequences which are not supported (parts of them appear on the screen). 3) It does not correctly handle some characters with more than one attribute set: a) Bold blink appears as bold. b) Bold underline appears as underline. c) Bold underline blink appears as underline blink. d) Blink reverse appears as underline. e) Bold reverse appears the same as reverse. f) There is no underline in reverse mode. g) There is no blink in reverse mode. I have a vt100 test program which can confirm these claims. The program is in the public domain (I originally got it from the net) so I can mail it to anyone who requests it. If there are enough requests I will post it to net.sources. In summary, while this review may sound a bit negative, I don't want to give the impression that I don't like Crosstalk. I do like it and I am using it (version 3.21 in TVI 920 emulation) right now to compose this article. I simply want to warn everyone that it's vt100 emulation mode has a few bugs in it. -- Dave Shanks ..!tektronix!ogcvax!metheus!teneron!shanks Teneron Corp.
